A screw 56' threaded into a sleeve 51 serves as additional securing means for the plate 31.

The end of reservoir 35 opposite valve 43 is provided with a normally closed pressure relief valve 60 adapted to seat in an aperture 6I in a threaded plug 62 positioned in a threaded aperture in an extending portion oi reservoir 35. Slots 54 are provided to permit the insertion of a suitable tool for removal or installation of plug 62. towards closed position (see Figs. '7, 8 and 9).

Means are provided for opening spring valve" 60 when plunger 3l is retracted and take the form of an apertured flanged bracket 66 (see Fig. 1l), the flanges 5'! of which are adapted to be inset in the end wall of the reservoir. The

A spring 65 normally biases valve 6!) u apertures are engaged by. a pivot pin 58 extend-A i ing from the fulcrurn ofY a bell crank lever 69, one leg l!! of which is adapted to open valve E@ when the other leg 'll is abutted by projection 34 of piston rod 3l. A channel l2 extending within portion 53 communicates with the hollow interior 73 of plug 52 to permit pressure relief from the reservoir.

The open end of slot 33 is protected as is the last described valve assembly against the ingress of dust or lint by means of an air pervious silk mat 'l5 apertured to permit extension of rod 3| the end of which is provided with a knob 16 to facilitate iinger grasp.

Referring back to Fig. 1, it will be seen that barrel 2U is threaded Vas at 11 for engagement with corresponding threads of a protective cap 'I8 having a conventional pocket clip 19.

From the foregoing the operation of the device should now be readily understandable. In normal use of the pen, with the parts as shown in Fig. 1, the reservoir 35 being assumed to contain ink, valve 43 is open and valve 60 closed as above described, and spring 26 holding valve 21 open, ink will ow by gravity to point 23.

When it is desired however to refill reservoir 35, cap 18 is removed and piston 30 is retracted by means of rod 3l. A pressure differential is thus created between pressure chamber 28 and atmospheric pressure which latter forces ink into chamber 28, valve 21 being open, simultaneous opening of valve 1:2@ equalizing the pressure in the reservoir. Reverse movement of piston 30 during nlling of the reservoir 35 serves to increase pressure in chamber 23 to a point sufcient to close valve 2'! and open valve :33,thus forcing ink into reservoir 35. Obviously a few additional movements of piston 3l) will serve to ll reservoir 35 to the desired degree.

It will now be seen that there is herein provided an improved fountain pen which accomplishes all the objects of the invention and others, including many advantages of great practical utility and commercial importance.
